This is from Wikipedia, but it's factual. He's related to six US presidents, plus Dick Cheney and Wild Bill Hickok. So yeah, our history is staged.

Stanley Dunham's distant cousins include six U.S. presidents - and another president who is Dunham's grandson: James Madison, Harry Truman, Lyndon Johnson, Jimmy Carter, George H. W. Bush and George W. Bush, plus Barack Obama, his grandson. Through a common ancestor, Mareen Duvall, a wealthy Huguenot merchant who emigrated to Maryland in the 1650s, Dunham is related to former Vice-President Dick Cheney (an eighth cousin once removed). Through Duvall and another common ancestor, Hans Gutknecht, a German Swiss from Bischwiller, Alsace whose three sons resettled in Germantown, Pennsylvania, as well as the Kentucky frontier in the mid-18th century, Dunham is President Harry S. Truman's fourth cousin, twice removed. Dunham and Wild Bill Hickok are sixth cousins, four times removed, through Jacob Dunham.
